5 Odors that Cause Migraines
Migraines are a type of headaches that can recur regularly. They usually cause mild to intense pain with a feeling of throbbing and pulsing on one side of the head. Migraines are caused by nerves that send pain signals into the brain and the surrounding vessels, causing the headaches. Migraine symptoms include the throbbing headaches, which are usually mild pain; if untreated, migraines can become severe, leading to a lot of pain, sensitivity to light, nausea, and vomiting. Most migraines last for about four hours, and they recede, but some go for up to three days. Migraines are usually made worse by physical activity, so one is advised to lie down in a dark room for a few hours until it gets better. There are many triggers for migraines; stress, hormonal changes, lack of sleep, hunger, and certain odors. Particular odors that can cause migraines to some people include: 1. Cigarette smoke Both active and passive cigarette smoke might cause migraines to some people. Cigarette smoke can cause migraines in several ways; cigarette smoke contains a lot of carbon monoxide; this compound is highly dangerous and, in small quantities, causes a reduction of oxygen in the brain hence causing migraines.
